The MRH 46-140 single-shaft equipped shredder is particularly suitable to shred high quantities of industrial wastes. The heavy structure makes the machine suitable to realize a heavy use.

A hydraulic control unit allows driving the pusher drawer. Thus, the product to be grinded is pushed towards a tools-holder rotor causing its crushing.

Thanks to a screen it is possible to select the final dimension of the shredder material.

Main features:

  • Power installed on the rotor: 75 kW (100 HP)
  • Power of the hydraulic control unit: 5,5 kW (HP 7)
  • Drive: by belts
  • Number of rotors: 1
  • Rotor diameter: 400 mm
  • Rotor length: 1400 mm
  • Number of reversible tools: 78
  • N° of usable tools sides: 4
  • Average number of rotor revolutions per min: 83
  • Weight: 7.000 kg
  • Production: 3,5-5 t/h.
  • Safety devices: emergency stop, drawer reversal system
  • Manufactured according to EC standards.
